Unfortunately, I'm quite pessimistic about any Mutualism gaining strength in my lifetime. Proudhon's practically lost to all anarchists beyond the "Property is theft!" line, Carson is usually written off by anarchist communists (who happen to make up most the anarchist movement, I believe) as reactionary or another bourgeois thinker, and the desire for a standard of liberty based in mutuality just isn't there in most people. Not only does the world have a view of liberty that necessitates security and restraint over free action, but no one seems to care about eliminating restraint to achieve free action, they'd rather try to balance the two.

And the notion of "X is causing Mutualism to happen" is not very likely in my opinion. The only people who believe that what is going on today is going to cause some sort of system to emerge are the people who already believe in that system. It's a confirmation bias. The AnCaps think 3D printing is the dawn of their system, Carsonian mutualists think the same of Mutualism, and communists think that robotics, among other things, are going to tear down Capitalism and bring out a worldwide revolution of Communism. Only one can be right, and there are far more that are wrong.
